  • Product overview

    Glutathione Peroxidase 1 (GPX1) in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Glutathione Peroxidase 1 protein in human serum, plasma, cell and tissue extracts.

    The SimpleStep ELISA® employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.

  • Notes

    GPX1 is a selenium-containing enzyme part of the glutathione system responsible for protecting against oxidative damage by catalyzing the reduction of hydroperoxides with glutathione. The homotetramer, GPX1, utilizes its selenocysteine-containing active site to primarily scavenge hydrogen peroxide. The dimerization of glutathione ultimately provides the electrons to reduce the active site, restoring GPX1’s activity. As a critical component of the regulation of oxidative species within cells, GPX1 is directly involved in metabolism, various cancers, and oxidative stress. This assay is specific to isoform 1 of glutathione peroxidase.

  • Function
    Protects the hemoglobin in erythrocytes from oxidative breakdown.
  • Sequence similarities
    Belongs to the glutathione peroxidase family.
  • Post-translational
    During periods of oxidative stress, Sec-49 may react with a superoxide radical, irreversibly lose hydroselenide and be converted to dehydroalanine.
